PURPOSE:To obtain the accurate measured values of glossiness and flatness of the same place by one measuring operation, by multiplying the measured value of glossiness by a correction factor in accordance with the property of the flatness so as to remove the effect of flatness. CONSTITUTION:When the flatness of a surface to be measured is bad considerably, a measured value of glossiness is smaller than a true value and an error increases. To cope with this state, correction is made in accordance with the degree of lessening from the true value. When a start switch is pressed, concretely, a switch circuit 14 is switched over by an instruction from a CPU 16. The CPU 16 measures flatness and glossiness sequentially and makes them to be shown as the results of measurement in a display. On the occasion, the flatness is displayed as it is, while, as to the glossiness, the measured glossiness multiplied by a correction factor corresponding to the flatness is displayed. This constitution enables the attainment of a surface property measuring apparatus wherein the glossiness of the surface to be measured, such as a coated surface, which is not affected by the flatness at all and the flatness thereof are measured and displayed simultaneously.
